Less Is More for Non-Dislocated Femoral Neck Fractures: Similar Results for Two versus Three Cannulated Hip Screws

Cannulated hip screws (CHS) can be used for the minimally invasive fixation of non-dislocated femoral neck fractures. Usually, three are inserted. This study aims to determine whether by two CHS leads similar results as CHS. Since January 2019, all patients with an indication internal were treated and followed prospectively. Results compared equal-sized control group who underwent (before 2019). The primary outcome was reoperation, while secondary screw dislocation. 50 Of these, 14 (28%) reoperation versus 13 (26%) in (p = 1.000). Reoperations included replacement, hemiarthroplasty, total prosthesis. Three major reasons pain due osteosynthesis material (n 15), coxarthrosis 4), cut out 3). Six weeks postoperative X-rays showed a dislocation 2 mm 1 0.330). Clinical outcomes very between groups. overall good; however, rate varied from 26 28%. majority reoperations replacements. Screw seems more prominent (2 mm). Fixation cannulated is acceptable treatment method fractures, insertion third does not lead superior clinical results.
